T Sleeping 

T Sleeping occurs several times in a persons life, most commonly when the person is in their late teens. While this person sleeps, their body is in the T-Pose, automatically meaning they’re having a wet dream about, Tyler Posey.

Person1: Did you have a wet dream about, Tyler Posey?
Person2: How did you know that??
Person1: You we’re totally T Sleeping last night.
